It's fascinating how people (the media likes to ask this..) offer an opinion about whether someone is capable of the crime. Like the neighbours did in the 9news interview. The neighbour's comments about his character and potential to do the crime were based on three seconds of waving to each other. Everyone is capable. The real question is not whether he was capable, but whether he did do it.
Using the 'struggled to deal with dying elderly patients' to explain unusual behaviour is an obvious potential cover. We don't know if he really was struggling. Maybe he was. If he worked at the same hospital for nine years, his work colleagues would have a view also of that. Queensland Health, his employer, has a free 24/7 Employee Assistance Program in place. Interesting to know if he ever actually used that service.
It sounds like the 'work stress' was potentially a good cover to do whatever he did, when he isolated himself. Bank records might show where he went (fuel, accommodation, where he purchased meals from) during those times.
I totally agree. I don't imagine "elderly patients dying at work" was his greatest stressor, although this is what he might have told his family. I think his moonlighting at various beaches & becoming more entrenched - in whatever it was he was doing there - lead him over the edge. Maybe stressors with work (performance), home (relationships), & wanting generally to expose himself (sexual deviancy) - maybe more realistic? Just MOO. I have no idea of course, but we know that burgeoning sexual fantasies can sometimes escalate to murder (with sexual motive) - moreso than elderly patients dying - unless he was responsible for the latter, eek! that could likely push him over the edge too? I'm not saying he was responsible for elderly patient's deathS, i just wonder what made him cross the line? I would love to know what the profilers have said !
